CONTINUOUS BRICK-KILN.

Specification of Letters Patent.

.Application filed March 1. 1907. Serial No. 359.950.

To all whom itfrnay concern:

Be it known thatwe, brick1naker, o Orchards Burnt Tree, Tipton, and RICHARD JASPER HAnLlNGToN and SAM- tUEL H1NroNcontinuous-kiln builders, both of 34 Oxfordroad, lest Bromwich, all in the count of Stafford, England, subjects of the Kingcfern oi; Great Britain, have invented a certain new and useful Improvement in Continuous BrickKilns and the Like, (for which we have applied for a patentin Great l\io.6,333,March16,1906,)0f which the following isa specification.

This invention-relates to those brick kilns in which the spent heat from one kiln is utilized for effecting the earlier processesconnected with successive kilns, thev present improvements consisting-of an arrangement of two or more grates or furnaces in conjunction with the respective kilns, in combination an arrangement of flues and'dam ers whereby the waste heat from the one iln may be kconveyed through the successive kilns until comletel spent, while at the same time the ieat rom the intermediate :grates or furnaces maybe gradually passed -l understood and more through the succeeding kilns as required for increasing the temperature until the necessary process of burning is effected. By this irnproved arrangement the starting of the intermediate assisted by the passing of the whole or a portion of the left heat from one or several coolmg chambers through the grates or lfurnaces' of a succeeding kiln.

' In order that this invention may be clearly easily carried into practice, reference may be had to the accompanying drawings which illustrate our invention as applied to a group 'of ten 'kilns which are consecutively numbered one to ten, .Figure 1 is a sectional plan showing one 'arrangement of a series of ten continuous 7 is a section on the line eing on the line 1-2 ofFi 2. Fig. 2 is a sectional elevation on the lne 3-4 of 1. Fig. 3 is a similar sectional elevation to that 'of Fig. 2 butshowing the preferred arra ement whereby the grates are arranged-.wit inthe span of the main arch of thekln. Fig. 4 is a sectional end elevation 0n the line 5'-6 of Fig. 1. Fig. 5 is a sectional end elevation on the line 7-8 of Fig. 1. Fig. 6 is a Section on the line 9-10 of Fig. 3. 11 \12 of Fig. 3. n carrying the invention into veffect the SAMUEL BARNETT,

grates or furnaces may also be thev kiln chamber 1- and ber 2 at one side of the kiln is provided with a centrallllue S and two side flues S extending le,l

kiln and the kiln chambers.

thwise of the e kiln chambers, 4numbered l to 10 inclusive, are arranged in two rows of five kiln chambers each on opposite sides of the central Hue' S with'the ki n chambers of each set between the central flue and one of the side lues. Ten of such drawings arranged in two series of fivev each, but the number may, of course, be varied to meet the requirements and capacity for which the kiln is designed.

Each kiln chamber is provided with furnaces A B at opposite sides thereof and referably transverse to the len th of the '111.' These furnaces, as shown in ig. 3, are built within the span ofthe arches of the kiln chambers, but they may, as shown in Fig. 2, be built within the supporting walls of the kiln chambers, municate with.the interior of the kiln chambers through apertures (L2 and b Each kiln chamber can be of those adjoining it, by closing the ampers of the connecting lues C, c" and d 'as hereinafter described. Each kiln chamber is ro-. vided with a set of these connectingiiues'll c', d formed below, the floor thereof to conduct the hot waste as from one kiln chamber to the other until the. gas

and, inthis case, they comres ectively. made 1n e endent' is spent, at which stage it is in the form of steam, and is di-4 Two sets of connecting ilues areprovided for each kiln chamber. One set consists of a central vflue C and three cross lines c', c', c', The centralilue C extends through the floor of the Akiln chamber l1 and beneath it parallel to the transverse sides thereof, and 1s connected with the central and side lues S and S by means of outlet ilu'es c3 having dam ers c, c5 respectively.. I The fines c provide with dempers c2 the flue C and extend beneath theiloor of partition separati them. The second set of f luesconsists o two luesd having o enings D through the floor of the kiln Chamb opposite side of the kiln chamber to the openings for the ilues c and. the liues d have. dam Vers d.' The lues d o' en into the kiln cham er 2 at the same side t ereof asthe lines c. The lues d are connected to the central and side flues S, S by outlet flues d 'into lthe kiln cham- .rected to Vthe stack ashereinafter described.

are connected with er 1, preferably at the vlO having dampers d5 and d3 respectively. The dampers dand c5 may be of conical form-d5 being shown in Fig. 4, and provided with suitable rods to eect -their-operation vfrom the top of the kiln.

Assuming the furnaces A, B, in Number 3 vkiln chamber are in operation, with the dampers c* and c5 closed, and the dampers c2 oened, the gases froni the furnaces pass if the heat bels ent, through the flues C, c,

to the centrali ues S or the side flues S or both central and side ilues by properly positioning the dampers c4 and c5 of the flues l, c of kiln chamber 5;

contents may be utilized asa hot draft for the burningof the furnaces of another kiln chamber, and in this case the dampers of the flues C, c and d are closed so that'the hotair from the kiln chamber will be obliged to 'pass through the furnaces to flues m and fiues M formed in the foundation of the kiln below theplane of the lines c and d', the dampers m of which are open for the purpose of allowing the hot gases to pass fromv the kiln chamber containing the burned contents to the furnaces of the kiln chamber to be burned-the dampers m of the remaining kiln' chambers being closed, each of the furnaces A, B f the various kiln chambers below the grate bars thereof being provided with flues m having dampers fm. arrangement the heat left in one kiln chamber after the burning of its contents may be utilized for the combustion of the fuel in the furnaces of any other kiln chamber. Taking, for instance, kiln chambersl and2, and assuming that kiln chamber 1 is full of articles that have v`'been burned and are to be cooled and kiln chamber 2 is to be burned. The dampers m of the nues M connecting the kiln chambers 1 and 2 are opened and the danipers of the remaining kiln chambers are closed and the dampers c2, c4, c5, 14,113 and d5 of kiln chamber 1 are also closed so that' the hot gases ass from the kiln chamber 1 to the kiln chamer 2 by way of the flue's M, a continuous current of vair being maintained lfrom kiln chamber 1- to kiln chamber 2 by kiln chamber 1 being opened to the atmosphere so that the air can pass over the contents of kiln chamber 1 and'enter furnaces A, B and fines m of that kiln chamber andthen pass to the flue M and then through the iues fm, and furnaces'of kiln chamber 2 to the interior of the last mentioned kiln chamber to assist the combustion of the fuel in the furnaces of kiln chamber 2-v By thisand then from the kiln chamber 2 by means of'iiues C, c.

In some cases it is desirable to pass the hot air from the flue M into the furnaces above the grate bars instead of throughthe latter and for this purposeflues m2, 'm3, 'mi arepro.-

vided in the partition walls separating the kiln chambers to communicate with one another and with the hot air flue M. The iiues m2 are provided with damper controlled outlet fines m5,- Tlie dam ers of the outlet flues 'm5 are operatedtliroug doors fm atthe end of the lues m2. In some cases air maybe Vled to the furnaces direct from the exterior of the kiln chamber through the flues m2 by 'opening the doors me.

I Figs. 6 and 7 illustrate slight modifications in the construction and arrangement of the ilues, -which are lrendered necessary when applying the same to kiln chambers with furnaces constructed as illustrated in Fig. 3.

. In these figures the fiues m2 are shown ex- The latent heat of one kiln'chamber-and its.

tending through4 the upright outer walls of the furnaces `and th'es'e ues are in this case only provided with a single damper m6.

-After the first kiln chamber has been fired from its furnaces, and when such fires are being let out, the kiln chamber next to it.of

the series can be fired, hot air being sup lied to the furnaces ofthe second.kiln c amber from the furnaces of 'the-preceding kiln chamber through the flues M, m. One row of kiln chambers is sometimes used, in this case the furnaces may be fired from both ends, the hot gases and hot air-beingconrow in the manner hereinbeforev described.
